Subject: [PATCH v2 11/12] arm64: dts: qcom: setup PDC as the wakeup parent for TLMM on SDM845
Date: Fri, 15 Nov 2019 15:11:54 -0700 [thread overview]
Message-ID: <1573855915-9841-12-git-send-email-ilina@codeaurora.org> (raw)
In-Reply-To: <1573855915-9841-1-git-send-email-ilina@codeaurora.org>
PDC always-on interrupt controller can detect certain GPIOs even when
the TLMM interrupt controller is powered off. Link the PDC as TLMM's
wakeup parent.
